Abstract

PCT No. PCT/FI94/00306 Sec. 371 Date Jan. 16, 1996 Sec. 102(e) Date Jan. 16, 1996 PCT Filed Jul. 1, 1994 PCT Pub. No. WO95/02762 PCT Pub. Date Jan. 26, 1995A rotator includes an axle and an associated rotor component having lamellar vanes. A case component surrounds the rotor component. Chambers arranged symmetrically in relation to the axle are disposed between the lamellar vanes. These chambers are pressurized by oil fed through feed and outlet openings connected to the chambers. Bearing members are arranged in an axial direction on both sides of the rotor component. A conical bearing carries the axial rotor load and is formed by a conical arrangement of juxtaposed surfaces defined by the case and axle. The case includes channels leading from the chambers to the conical surfaces for communicating pressurized oil thereamong. The conical arrangement includes spaced gaskets. Oil pressure applied between the conical surfaces raises the axle off the case. In the absence of oil pressure, the conical surfaces lock as a result of friction between the case and axle.
